Dear All,
Following is my project brief:
1.MCU controlled switching is used for High current (250mA).
2.Load 1 to 8 will be switching ON/OFF in chain-sequence one by one.
3.Load 1 will be ON for 200uS while rest of the loads will be OFF. then Load 2 will be ON for 200uS while rest of the loads will be OFF and so on...
4. Schematic is in attachments
Requirement..
A. Instead of the switches shown in schematic, a chip is required to perform high current, high speed switching (5.1KHz).
B. What kind of chip/chip array is best suitable for this time of applications?
Darling array, MOSFET etc..??
C. Can following ICs be used for this application?
ULN2803
DMP2240UDM
Please advice...
